Please use python language in simplest functions if possible - when rounding to two use the rounding function. thank you

Chapter 04 Sales Tax Calculator Create a program that uses a separate module, named "Calculations Module.py", to calculate sales tax and total after tax. This module will need to be imported into the Main Module. Console Sales Tax Calculator ENTER ITEMS (ENTER -99 TO END) Cost of Item: 36.99 Coat of ites: 29.50 Cost of Item: 16.59 Cost of item: -99 Total: 83.00 Sales tax 4.90 Total after tax: 08.06 Again? () ENTER ITEKS (ENTER -99 TO KND) Cost of itemi 152.50 cost of item: 59.80 Cost of itent -99 Total: 212.3 sales tax: 12.74 Total after tax: 225.04 Again? [Y) 1 Thanks, byer Specifications The main module will get the input from the user, calculate the total of all the items, and print the output as shown in the sample output above. Divide the code in this module into functions that will make the code casier to read and maintain . . The sales tax rate should be 6% of the total. Store the sales tax rate as a constant in the separate calculations module. This module will also contain two functions that (1) calculate the sales tax and (2) the total after tux. The functions will take the total cost of all items as the input argument and round the results to a maximum of two decimal places Add docStrings to this calculations module. Assume the user will enter valid data
